Cushing's Syndrome: Corticotropin-Releasing Hormone

Topic Overview

The corticotropin-releasing hormone (CRH) stimulation test
helps find out if a
pituitary tumor may be causing
Cushing's syndrome. It is sometimes done with an inferior
petrosal sinus sampling (IPSS) test.

In these tests, a small tube called a catheter is used. A health professional uses it
to collect samples from blood vessels coming from the pituitary gland near the brain and also from a vein in your arm. First you will get a shot of CRH. Then samples of your blood near your pituitary gland and from your arm are taken.
